Title: Flow-through humidifier
Inventor: MENASSA CHERIF
IPC: F24F6/04
Filed: 2000-06-30
Granted: 2007-09-04
Abstract: The present invention provides flow-through humidifier device having a frame assembly adapted to be secured onto an air supply duct and having a back wall with an air inlet opening, two side walls, one with an air outlet opening, top and bottom walls and a front cover wall, an evaporator assembly including a pad, a water supply member and a water drain member to supply unfiltered water at standard city pressure to and collect any excess of water from the pad member respectively. The water supply member includes a valve controlled by an air temperature electronic controller. The latter is electrically connected to a temperature sensor sensing the temperature of the air flowing and timely pulses the valve to open when the air temperature is above a pre- determined set temperature and allow for water to humidify the pad. The top and bottom walls of the frame assembly are preferably a mirror image of each other such that the humidifier can be mounted in either an upright or an upside down orientation depending on the right or left hand side desired position of the air outlet opening respectively.
Patent CA-2316982-C (CA)
Title: Ink cartridge and printer using the same
Inventor: SHINADA SATOSHI
IPC: B41J2/165
Filed: 1999-11-02
Granted: 2008-08-19
Abstract: In an ink jet printer of the present invention, in order to reduce the manufacturing cost, an inexpensive EEPROM enabling only sequential accesses is applied for storage elements incorporated in a black ink cartridge and a color ink cartridge. The data array of a memory cell included in each of the storage elements mounted on the ink cartridges is determined in such a manner that a second storage area, in which rewritable data, for example, data on remaining quantities of inks in the ink cartridge, are stored, is accessed prior to a first storage area, in which read only data are stored. This configuration enables the rewritable data to be securely written into the second storage area even aft er a power-off operation. The second storage area has two memory divisions allocated to each ink, that is, a first ink remaining quantity memory division and a second ink remaining quantity memory division. Latest data on the remaining quantity of each ink is alternately written into these two memory divisions. Alternatively, the latest data on the remaining quantity of each ink is written into these two memory divisions in a duplicated manner. Each ink remaining quantity memory division has a write complete flag to determine whether or not a writing operation has been completed normally in the ink remaining quantity memory division. This arrangement enables the remaining quantities of the respective inks to be monitored accurately and continuously.

Granted: 2005-11-22
Abstract: An improved method of parent ion scanning is disclosed. In one embodiment a quadrupole mass filter 3 upstream of a collision cell 4 is arranged to operate in a highpass mode. Parent ions transmitted by the mass filter 3 are fragmented in the collision cell 4 and detected by an orthogonal time of flight analyser 5 which obtains a daughter ion mass spectrum. Ions having a mass to charge ratio below the cutoff of the mass filter 3 are identified as daughter ions, and candidate parent ions may then be discovered and their identity confirmed by obtaining corresponding daughter ion spectra. In a second embodiment, the collision cell 4 alternates between high and low fragmentation and candidate parent ions can additionally be identified on the basis of the loss of a predetermined ion or neutral particle.

Abstract: Modifications in the sequence of Aequorea wild-type GFP provide products having markedly different excitation and emission spectra from corresponding products from wild-type GFP. In one class of modifications, the product derived from the modified GFP exhibits an alteration in the ratio of two main excitation peaks observed with the product derived from wild-type GFP. In another class, the product derived from the modified GFP fluoresces at a shorter wavelength than the corresponding product from wild-type GFP. In yet another class of modifications, the product derived from the modified GFP exhibits only a single excitation peak and enhanced emission relative to the product derived from wild-type GFP.

Title: Turbo code interleaver using linear congruential sequences
Inventor: LING FUYUN
IPC: H03M13/27
Filed: 1999-12-03
Granted: 2009-05-19
Abstract: A turbo code interleaver (100) using linear congruential sequences may be employed as a two-dimensional interleaver (16) in a turbo coder (10) that also includes first and second constituent encoders (12, 14). The interleaver (16) and the first encoder (12) are each configured to receive input bits. The first encoder (12) produces output symbols (22, 24) therefrom. The interleaver (16) receives the input bits (20) sequentially by row. A linear congruential sequence recursion algorithm within the interleaver (16) serves to pseudo-randomly rearrange, or shuffle, the bits within each row of the interleaver (16). The bits (26) are then output from the interleaver sequentially by column. The second encoder (14) is configured to receive the interleaved bits from the interleaver. The second encoder (14) produces output symbols (28) therefrom. The two streams of output symbols (22, 24) are multiplexed together, with appropriate puncturing. If desired, the linear congruential recursion sequence can be generated in reverse. Also if desired, a bit reversal technique can be used in the interleaver (16) to rearrange, or shuffle, the rows of the interleaver (16).

Abstract: Cette invention a trait à une installation de traite conçue pour la traite d'animaux, de vaches notamment, les dispositifs permettant de recueillir le lait, de préférence sous forme de gobelets de trayeuse, étant fixés aux tétines de l'animal et le lait étant extrait par dépression. Le lait est transporté par un système de conduite (31) vers un équipement de stockage comprenant une cuve de refroidissement (30). Aux fins du nettoyage, le système de conduite de lait de chaque dispositif de collecte du lait est isolé de la cuve de stockage de lait par un système de clapet (32) et ce, afin de procéder au nettoyage dudit système de conduite du lait. Le procédé selon l'invention se caractérise par le fait qu'il permet d'éviter tout transfert de détergent dans le lait stocké dans la cuve et ce, par la création d'une différence de pression entre les deux liquides. On crée cette différence de pression, de préférence, en reliant le liquide de nettoyage à la source de vide (4) de l'installation de traite.

Abstract: Cette invention se rapporte à un appareil d'affichage comprenant une source d'image effectuant un mouvement de balayage autour de deux axes. Pour décaler le mouvement autour du premier de ces deux axes pendant le mouvement de  balayage autour du second axe, cet appareil utilise une structure destinée à produire un mouvement de décalage autour du premier axe à une vitesse de balayage égale à deux fois la vitesse de balayage autour du second axe. Le balayage avec décalage peut se présenter sous la forme d'une rampe ou de tout autre type de mouvement. Dans un mode de réalisation, le mouvement de décalage est un sinusoïde résonant. Le mouvement de décalage peut être produit par un scanner auxiliaire, tel qu'un scanner mécanique, un scanner piézo-électrique, un scanner MEM ou tout autre scanner. Etant donné que le mouvement de décalage est très petit, le scanner auxiliaire peut fonctionner avec un très petit angle de balayage.
